what is the best oil fliter to use

 

K@N's flow the best. That's what you need when driving the car hard. A more restrictive filter will switch into bypass mode to maintain oil flow.

I agree that the K&N oil filter is one of the best. I use the long version and 6qts or oil.

 

I use the Mobil 1 filter m1-206

 

I also like the mobil 1 filter + mobil 1 oil.

 

I just did a change and used the M1. Couldn't find the K&N. Man it sukked getting the old filter off. It is so small in diameter that none of my filter wrenches would work. And tight to the oil pan. I'll have same problem when I change this filter. K&N's have a nut on the end. For just that reason I would recommend them.

IMO, there are filters just as good as the K&N made by the same company for 1/4 of the price.

 

lol! you beat me to the link! that excel chart is awsome! the k&n does have a nice balance of flow vs. filtration and is built like a tank. the purolator premium plus looks to be another well balanced filter, and would seem to be an excellent choice that is cheap and easy to find.

 

But you failed to mention that the Mobil 1 filter got a very good review too!!

 

i just use the ac delco filter. i think its pf44 or pf46. i never got on my Z hard anyways. never had any problems with it.

 

there are more than a few that are worthy filters, if you check the excel chart out. i used the purolator premplus as an example because it has good filtration, flows like gangbusters, can be found at any advance auto and is really, really cheap.

like with most things filtration, it is a trade-off between flow and filtration. imo, i think that the m1 and certainly a filter like the purolator pureone are too restrictive for my ls1 and i would never use them. if someone values filtration above all else, then the pureone, fram toughguard and the ac/delco upf series would be excellent choices. someone that only cares about flow might want to look elsewhere.

personally, i am looking for neither extremes... i am willing to give up a little filtration for better flow. someone else might be willing to give up a bit of flow for better filtration. what ppl that downloaded the chart should check out is the average large pore size vs the flow and make draw their own conclusions about which is right for them.

 

Including Wal-mart's Tech filters

 

Another vote for the Wal-Mart SuperTech filter in the longer size.

 

I use AC DELCO Part # PF59, in my 5.3, 4.8, & 5.7 LS1's!!!! I am happy with the filter and for added protection, I use a FILTER-MAG!!!!
